LOAD TRANSFERS IN MULTI-AXLE PLATFORMS WITH GOOSENECK CONNECTIONS
The transportation of overdimensional or overweight loads by road is often necessary, and has the potential to cause a lot more damage to roads and bridges than normal trucks. This report presents the findings of an investigation into the load transfers in the platforms used to carry such loads. Two load platforms were instrumented and driven over typical test circuits. One of the platforms could be altered to different load sharing configurations. It was found that the so-called 'two point' configuration had the best load transfer characteristics--given the lowest dynamic loads to the road surface and to the towing vehicle. A 'compensating gooseneck' configuration was also tested, also giving favorable load transfer characteristics. As a result of this test program, we are in the position to recommend the use of Two Point and Compensating Gooseneck load platforms for the transfer of indivisible loads.
